Title: Method and Apparatus for Forming a Double Walled Thermoplastic Tube with Integral Bells
Inventor: LUPKE MANFRED A A
IPC: B29C48/13
Filed: 1992-06-29
Abstract: A double wall plastic pipe is produced from an extruder with a nozzle having a first orifice and a second orifice downstream of the first orifice feeding into a moving mold tunnel having a first region with a corrugated mold surface and a second region with a belled mold surface. The second region also has openings through the mold wall. A first parison of molten thermoplastic material is extruded from the first orifice into the mold tunnel with the first parison being forced against the corrugated mold surface to shape alternating crests and troughs and against the belled mold surface to shape a bell in the first parison in forming respectively corrugated and cuffed pipe parts. The first parison is ruptured through the mold wall openings to produce an air escape in the bell of the first portion. A second parison of molten thermoplastic material is extruded from the second orifice into the mold tunnel and the second parison is forced to lie against and form a solid laminate with the troughs and the bell in the first parison. Air between the second parison and the bell of the first parison is expelled out of the pipe through the air escape passage in the first parison of the mold tunnel through the mold wall openings in the belled mold surface.

Filed: 1992-09-24
Abstract: ABSTRACT OF THE DISCLOSURE A simple and low cost system for temporarily but securely holding together stacked document sheets in discrete "packaged" sets, for reproduction job collection and distribution without permanent binding or sheet damage. It isparticularly suited for automatic application to collated copy sheet output of acopier, shared printer or facsimile machine. Each job or selected output stack of printed sheets may be temporarily bound by small adhesive tape segments, much smaller than the sheets, so as to maintain the sheet set integrity under distribution and other handling, yet allow removal of the tape whenever desired to unbind the stacked sheets without any damage to the sheets, unlike stapling or other such permanent binding. It has been found that by wrapping one small tape segment around each of two opposing edges of a job stack of multiple sheets, with adhesion of at least part of each tape segment only to small opposing edge areas of the top and bottom sheets of the stack, that a whole job stack can be integrally held together for convenient set separation, handling and distribution, yet separated at any time, unmarked and undamaged, by easily peeling or tearing off the tape segments. Encoding tape segments with set identifying indicia, and/or tape removal assistance, and cover sheets, may be compatibly provided.

Title: Method and device for guiding a leader of a web in a paper machine
Inventor: KIVIMAA JUHA
IPC: D21G9/00
Filed: 1993-03-04
Abstract: ABSTRACT    The invention relates to a device and method in a paper machine for guiding a web and in particular in guiding a leader of the web.  The device operates in a paper machine in the area between a center roll of the press section and a separate press nip in the press section.  The separate press nip is formed between a smooth-faced upper roll and a hollow-faced lower roll.          Around this lower roll, a lower felt of the separate press is placed and runs from a suction-transfer roll placed at the proximity of the center roll as a straight run into the separate press nip.  At the initial end of the straight run of the felt of the separate press nip, in connection with the guide roll, air-transfer devices are arranged, by whose means a reduced pressure is produced at least across the width of the leader in connection with a closing inlet nip between the felt and the leader and/or in connection with an opening outlet nip defined between the guide roll and the straight run of the felt.

Abstract: Each node in a multinode communication system is provided with programming to act as a Set Manager for a given set of nodes  and users.   Functions  of  the  Set Manager  include operation  processes  for  creating  distribution  trees  for efficient  multicast  and  bandwidth  reservation  tasks. Because set membership is not necessarily fixed or accurate at the time the distribution tree  is created,  the Tree Leader  task  that  creates  and maintains the  trees  needs accurate and updated information showing the number of users at  the  nodes  it  serves  which  are participating  in  the distribution tree.   The  count  of  active  users  at  nodes served by the Tree Leader is provided in response to an indicia established at the time the Tree Leader sets up the tree.  Each Set Manager at a given node monitors for changes in  set  membership  and  link  failure  and  notifies  the requesting  Tree  Leaders  for  each  tree  in  which  it participates whenever changes in the number of users either by joining or leaving the set or link failures occur by direct communication between the Set Managers and the Tree Leaders without requiring intervention of other elements in the system.

Title: Method and circuit arrangement for checking the observance of prescribed transmission bit rates in an atm switching equipment
Inventor: FOGLAR ANDREAS
IPC: H04L12/56
Filed: 1993-04-21
Abstract: ABSTRACT OF THE DISCLOSURE       A check of the observance of prescribed transmission bit rates in an ATM switching equipment occurs using counter devices (RAM1, ALU) working according to the "leaky bucket" principle. These are individual allocated to virtual connections via the switching equipment (VA).  The momentary counter readings of these counter devices are respectively decremented by a variable count value only upon  arrival  of  a  message  cell  of  the  respective  virtual connection.  This variable count value is proportional to the time difference between the arrival time of the respective message cell and the arrival time of the message cell of the same virtual connection that immediately preceded it.   The transmission bit rates determined for the virtual connections are thereby allocated to defined bit rates classes. On the basis of this allocation, an individual proportionality factor that is utilized for the duration of the existence of the respective virtual connection for the calculation of the variable count value is calculated for each of the virtual connections on the basis of this allocation.

Abstract: A bag type device (2) for extracting water from oil includes a bag (3) with an outer layer of felt (20) lined by at least one layer (22) of water absorbing laminate. The interior of the bag is composed of a plurality of slit sheets of water absorbing laminate forming a plurality of finger-like strips (35) depending from adjacent the top of the bag.   The strips are preferably longer than the length of the bag. The bag and the water-absorbing layers within the bag are supported by a wire ring (30) stitched into a hem around the open upper end of the bag. As oil is passed through the bag, the finger-like strips provide an increased surface area for absorption of water from the oil. The strips can expand inwardly and toward the oil flow to prevent back-pressure build up within the bag.
